METHYL PROPYL KETONE ICSC: 0816 2-Pentanone Ethyl acetone MPK C5H10O / CH3(CH2)2COCH3 Molecular mass: 86.1 ICSC #    0816 CAS #     107-87-9 RTECS # SA7875000 UN #        1249 Types of Hazard/ Exposure Acute Hazards/ Symptoms Prevention First Aid/ Fire Fighting FIRE Highly flammable. NO open flames, NO sparks, and NO smoking. Alcohol-resistant foam, powder, carbon dioxide. Explosion Vapour/air mixtures are explosive. Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding). Do NOT use compressed air for filling, discharging, or handling. In case of fire: keep drums, etc., cool by spraying with water. Exposure  •Inhalation Cough. Dizziness. Drowsiness. Dullness. Headache. Sore throat. Ventilation, local exhaust, or breathing protection. Fresh air, rest. Refer for medical attention.  •Skin Dry skin. Redness. Protective gloves. Protective clothing. Remove contaminated clothes. Rinse skin with plenty of water or shower.  •Eyes Redness. Pain. Safety goggles, or eye protection in combination with breathing protection. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •Ingestion Abdominal pain. Nausea. (See Inhalation). Do not eat, drink, or smoke during work. Rinse mouth. Do NOT induce vomiting. Refer for medical attention. Spillage Disposal Storage Packaging & Labelling Ventilation. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT wash away into sewer. Fireproof. UN Hazard Class: 3 UN Packing Group: II METHYL PROPYL KETONE ICSC: 0816 Important Data Physical State; Appearance: COLOURLESS LIQUID , WITH CHARACTERISTIC ODOUR. Physical Dangers: The vapour mixes well with air, explosive mixtures are easily formed. As a result of flow, agitation, etc., electrostatic charges can be generated. Chemical Dangers: Reacts violently with strong oxidants, strong bases, amines and isocyanates. Occupational Exposure Limits: TLV: 200 ppm; 705 mg/m3 (as TWA); 250 ppm; 881 mg/m3 (as STEL) (ACGIH 1997). MAK: IIb (not established but data is available) (DFG 2007). OSHA PEL: TWA 200 ppm (700 mg/m3) NIOSH REL: TWA 150 ppm (530 mg/m3) NIOSH IDLH: 1500 ppm See: 107879 Routes of Exposure: The substance can be absorbed into the body by inhalation of its vapour and by ingestion. Inhalation Risk: A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C. Effects of Short-Term Exposure: The substance irritates the eyes, the skin and the respiratory tract. Exposure above OEL could cause lowering of consciousness. Effects of Long-Term or Repeated Exposure: Repeated or prolonged contact with skin may cause dermatitis.
